Magnetostratigraphy of ODP Leg 108 sites@en

This paper presents the magnetostratigraphic results from Leg 108 of the Ocean Drilling Program. Measurements made with the shipboard \"pass-through\" cryogenic magnetometer on whole cores and archive halves are combined with those made on discrete samples; these measurements constitute the paleomagnetic data base for the Leg 108 cores. Polarity determination on unoriented, low-latitude cores is somewhat subjective; we rely heavily on the available biostratigraphic data and document our line of reasoning where appropriate. The interpretations presented here, therefore, are compatible with the available biostratigraphic information; they are also in substantial agreement with orientation information where available.本论文报道了大洋钻探计划（Ocean Drilling Program）第108航次的地磁地层学研究结果。研究将船载‘通道式’低温磁力仪对完整岩芯及存档半芯的测量数据，与离散样品的测量数据进行整合；上述测量数据构成了第108航次岩芯的古地磁数据库。针对无定向低纬度岩芯的极性判定存在一定主观性，因此研究团队大量依托现有生物地层学数据，并在适宜之处完整记录了其推理过程。据此，本文提出的解释与现有生物地层学信息兼容；在有定向数据可用的情况下，其结论也与定向数据大体一致。
